SPECIFICATION forming part of Letters Patent No. 676,827, dated June 18, 1901.

Application filed March 1, 1899. Serial No. 707,277. (No model.)

To all whom it may concern:

Be it known that I, ADAM O. VVILLIAMS, a resident of Ravenna, Portage county, and State of Ohio, have invented certain new and useful Improvements in Riveting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to riveting-machines such as are used for riveting or securing to gether layers of leather, rubber, or the like.

My invention consists in the peculiar construction of the machine whereby the parts thereof are easily and economically constructed and whereby the parts may be easily and economically assembled, all of which will be hereinafter fully set forth and claimed.

In the drawings, Figure I is a sectional view taken longitudinally and vertically through the body of the machine, illustrating the interior construction of the machine and the relation of its operative parts. In this View the movable plunger is illustrated in such position as it assumes before the machine is applied to perform its function. Fig. 11 is a like sectional view illustrating the parts of the machine in the position which they assume during the operation of riveting. Fig. III is a View in rear elevation of the body, showing the opening in the rear of the frame adapted to receive the plunger-lever in assembliug the parts.

In the drawings, A represents the frame of the machine, provided with upper jaw A and lower jaw A. The upper jaw A is provided at its outer or forward end with an adjustable anvil, which is constructed in the form of a screw A and is provided at its upper end with a mill-head a for operating it. The anvil portion of the screw A is pointed, as at or, and is also recessed in the usual manner, so as to properly enter and spread the rivet. This lower jaw A of the machine is formed with a recess B for the purpose of receiving and containing the forward end of a plungerlever O and is also provided with an orifice B at its upper forward end of sufficient here to receive the rivet and at the same time receive, guide, and allow of the free vertical movement of a plunger G which is located directly beneath the anvil-screw A The plunger 0 is preferably headed or provided with a flange c to prevent the same from dropping from the machine and provide a proper abutting surface for the forward end of the plunger-lever O.

D represents a spiral spring, which is located to the rear of the plunger O and between the forward end of the plungerdever O and the upper wall of the lower jaw B. The spring D is held in position by having its upper end inserted in a recess Z), formed in said upper wall. At the lower end the spring D surrounds a stud d, formed upon the upper face of the plunger-lever O.

E E represent pivotal studs cast or formed in the side walls of the recess B. The studs E E act as the fulcrum for the plunger-lever O and are engaged by flanged pockets F F, located, respectively, at either side of said plunger-lever. The formation of the flanged pockets F is such that while they form a bearing or fulcrum portion for the plunger-lever 0 they are opened at their lower portions.

G G represent guide-lugs, secured, respectively, upon the opposite sides of the plungerlever C. The ribs G G are suitably placed so as to receive and be guided by curved ribs H H, located upon the respective sides of the recess B. The function of the ribs G G of the plunger-lever O and the curved engaging ribs H H is to retain the plunger-lever O in proper position in the recess B and at the same time allow of the proper sweep of said lever during the operation of riveting.

J represents the rear opening of the recess B, which is formed large enough to admit of the insertion of the plunger-lever C and allow said lever to be so manipulated as to assemble the parts into the position illustrated in Figs. I and II of the drawings.

By a construction made according to, my invention the upper jaw A and lower jaw A and the plunger-lever C may be finished in the casting, and it will not be necessary to fit the aforesaid parts for the purpose of assembling the same except to cast these parts.

What I claim is In ariveting-too1,the combination of a housing provided with an integral handle, curved ger resting on the inner end of said lever and ribs H, H, located in the interior of said housan anvil located above said plunger, substaning and formed integral therewith, lugs E, E, tially as described and for the purpose set projecting inwardly from the sides of said forth.
